To investigate the optimal position in application of acoustic pharyngometry to detect the pharyngeal condition and to assess its therapeutic effect on obstructive sleep apnea hypopnea syndrome(OSAHS). Eight adult males were assigned to the normal group, and 57 male patients with OSAHS diagnosed by polysomnograhy(PSG) were assigned to the snoring group. Of the snoring group, 11 patients who were diagnosed severe OSAHS underwent low-temperature plasma uvulopaltopharyngoplasty(UPPP) and coblationchanneling of the tongue(CCT), were assigned to the operation subgroup; 8 patients underwent continuous positive airway pressure(CPAP), which was assigned to the CPAP subgroup.

Obstructive Sleep Apnea Syndrome Abstract. The obstructive sleep apnea syndrome (OSAS) is a disorder of the control of breathing in which repetitive collapse of the upper airway during sleep leads to frequent apneas/hypopneas with cyclic oxygen desaturation and arousals. Sleep is fragmented and unrefreshing. Read More

Obstructive sleep apnea (OSA) is a sleep disorder resulting from the repetitive narrowing and collapse of the upper respiratory tract. The results of previous epidemiological studies confirm a significant impact of OSA on the health situation around the world. Untreated OSA is associated with many adverse health effects, such as hypertension, coronary artery disease, stroke, atrial fibrillation, congestive heart failure, and daytime sleepiness. Read More

Background: Obesity is one of the most prominent risk factors for obstructive sleep apnea (OSA). Weight loss decreases the number of shorter respiratory events (<40 s), whereas the number of longer events remains almost unchanged. However, it is unknown how body mass index (BMI) affects individual obstruction event severity within OSA severity categories when age, sex, smoking, daytime sleepiness, snoring, hypertension, heart failure, and sleeping posture are considered.

Obstructive sleep apnea syndrome (OSAS) is caused by periodical upper airway occlusion during sleep resulting in snoring, episodes of apnea and excessive daytime sleepiness. OSAS is a risk factor for hypertension, arrhythmias, conduction disorders as well as stroke, coronary artery disease, chronic heart failure and pulmonary hypertension. Early polygraphy and polysomnography and continuous positive airway pressure (CPAP) treatment reduce risks of cardiovascular diseases (CVD) in patients with OSAS. Read More

Sleep-disordered breathing has a spectrum of severity that spans from snoring and partial airway collapse with increased upper airway resistance, to complete upper airway obstruction with obstructive sleep apnea during sleeping. While snoring occurs in up to 20% of children, obstructive sleep apnea affects approximately 1-5% of children. The obstruction that occurs in obstructive sleep apnea is the result of the airway collapsing during sleep, which causes arousal and impairs restful sleep. Read More

Older adults undergo gradual changes in their sleep patterns. It is important to differentiate normal age-related sleep changes from sleep disorders. Because sleep disorders can impact an older adult's day-to-day life and contribute to various comorbidities, these patients should be carefully screened by using a detailed medical history, combined with a detailed sleep history.

Introduction: Obstructive sleep apnea syndrome (OSAS) is defined by recurrent episodes of significant reduction or absence of the oro-nasal airflow during sleep, in the presence of thorax and abdominal movements and snoring. The pathophysiological consequences of intermittent hypoxia determined by OSAS are represented by systemic inflammation, the release of free oxygen radicals and activation of the sympathetic nervous system. Cardiac arrhythmias are a frequent comorbidity in patients with OSAS. Read More

Numerous studies report that difficulty breathing through the nose is associated with reduced sleep quality, increased daytime dysfunction, and increased risk of snoring and obstructive sleep apnea (OSA). Additionally, chronic nasal obstruction often complicates and limits successful medical device therapy for OSA, particularly with continuous positive airway pressure (CPAP). When medical evaluation and management of the nose is inadequate, surgical therapy to lower nasal resistance has been shown to substantially improve sleep and breathing outcome measures. Read More

We aimed to identify novel molecular associations between chronic intermittent hypoxia with re-oxygenation and adverse consequences in obstructive sleep apnea (OSA). We analyzed gene expression profiles of peripheral blood mononuclear cells from 48 patients with sleep-disordered breathing stratified into four groups: primary snoring (PS), moderate to severe OSA (MSO), very severe OSA (VSO), and very severe OSA patients on long-term continuous positive airway pressure treatment (VSOC). Comparisons of the microarray gene expression data identified eight genes up-regulated with OSA and down-regulated with CPAP treatment, and five genes down-regulated with OSA and up-regulated with CPAP treatment.

Obstructive sleep apnea syndrome (OSAS) is characterized by the recurrent cessation (apnea) or reduction (hypopnea) of airflow due to the partial or complete upper airway collapse during sleep. Respiratory disturbances causing sleep fragmentation and repetitive nocturnal hypoxia are responsible for a variety of nocturnal and daytime complaints of sleep apnea patients, such as snoring, daytime sleepiness, fatigue, or impaired cognitive functions. Different techniques, such as magnetic resonance imaging, magnetic resonance spectroscopy, and positron emission tomography, are used to evaluate the structural and functional changes in OSAS patients.
